What is the importance of informal fallacies in the study of logic?

More than just identifying flaws, the primary purpose of studying fallacies is to avoid falling foul of them. By showing why and when a certain way of reasoning does not support the truth of the conclusion, that is, does not offer enough convincing evidence for it, the study of fallacies becomes inescapable.
